研究了骨胶原蛋白酶解物的总抗氧化能力、羟自由基(·OH)清除作用和抑制超氧阴离子自由基的能力.通过与谷胱甘肽(GSH)的比较发现,溶液质量浓度在100～150 mg/mL时,该骨胶原多肽的总抗氧化能力为GSH的71.92%.溶液质量浓度在2.5～20 mg/mL时,该多肽羟自由基清除作用为谷胱甘肽的1.36倍.溶液质量浓度为10～150 mg/mL时,多肽抑制超氧阴离子自由基的能力低于谷胱甘肽.

In this manuscript, the effect of bone collagen peptide and glutathione （GSH） on the total antioxidant capacity, hydroxyl radical scavenging and superoxide anion free radical inhibition was carefully investigated. It was found that this peptide exhibited： （1） 71.92% total antioxidant capacity that of GSH at the range of 2.5 mg/mL-20 mg/mL; （2） 1.36 times hydroxyl radical scavenging that of GSH at the range of 2.5 mg/mL-20 mg/mL; （3） But superoxide anion free radical inhibition of this peptide was lower than that of GSH at the range of ...
